Stephen's thinking on this is good (taking an old principle and applying it to a different concept
of the spectator doing the work) but this could have been a 20 minute video! And, t seems to me that
this trick should be performed standing, to psychologically "cover" the fact that your hand is in
your pocket - sitting down it just looks unnatural. Finally, production quality is less than
attractive - looks like he just got up (in his t-shirt and cargo pants), ran downstairs to the
basement and shot the video. If you can get past that, the video will teach you about a concept that
every magician and mentalist should know.
